Heat Safety & Style Tips for Dryden and Vermilion Bay Residents

When Mother Nature turns up the heat like this, it’s time to turn up your hydration, too. Stick to light, loose, and breathable clothing in pale colours. Wide-brimmed hats, sunglasses, and a good water bottle should be your trusty companions whether you’re headed to the boat launch, the trails, or just the backyard.

Limit strenuous outdoor activities to early mornings or later in the evening when temperatures are slightly less punishing. And, of course, remember that no one—not even your beloved Labrador—should be left in a parked car during this heat.
